Obama acknowledged that America has a history of robust partisan politics. "We've been fighting about the proper size and role of government since the day the framers gathered in Philadelphia. We've battled over the meaning of individual freedom and equality since the Bill of Rights was drafted," said the president. He bemoaned the "demonization of the opposition," attacks that get picked up in the 24/7 media echo-chamber that amplifies "the most inflammatory soundbites louder and faster than ever before."

Obama spoke of the polarization that comes when people only expose themselves to opinions and viewpoints they agree with. Students were challenged to actively seek out information that challenges our assumptions and our beliefs, perhaps we can begin to understand where the people who disagree with us are coming from.

If you're somebody who only reads the editorial page of The New York Times, try glancing at the page of the Wall Street Journal once in a while. If you're a fan of Glenn Beck or Rush Limbaugh, try reading a few columns on the Huffington Post website. It may make your blood boil; your mind may not be changed. But the practice of listening to opposing views is essential for effective citizenship. It is essential for our democracy.

The president noted the serious arguments about healthcare, war and taxes, debates that stir great passion from both sides. To him, it’s important for all to be heard without tearing each other down.

You can question somebody's views and their judgment without questioning their motives or their patriotism. Throwing around phrases like “socialists” and “Soviet-style takeover” and “fascist” and “right-wing nut” -- that may grab headlines, but it also has the effect of comparing our government, our political opponents, to authoritarian, even murderous regimes.”

Strident attacks that were once found only among left- and right-wing fringe groups have gone mainstream.

Said Obama: "The problem is that this kind of vilification and over-the-top rhetoric closes the door to the possibility of compromise. It undermines democratic deliberation. It prevents learning –- since, after all, why should we listen to a 'fascist,' or a 'socialist,' or a 'right-wing nut,' or a 'left-wing nut'?"
